ED is extremely unintuitive and that's more the issue than the difficulty, which is also a bit steep at first. Now, I'm the type that researches, watches YouTube videos, reads wikis, all of that before even buying a game, but most people don't do this, nor should they need to.
Sure, I figured it all out after several pretty disastrous false starts, but many new folks are going to be completely lost. It is a real issue, not to be ridiculed or taken lightly, as a whole brigade of new folks are about to try ED soon.
